A number of people are asking, specially those folks not so familiar with computer or with technology in general – “how do i make my computer run faster?”

Reasons a computer runs Slow

Here are a couple of reason why a computer run slow:

1. Old model
2. Not enough ram to accommodate application
3. A computer virus

First of all, if you bought a hand me down, second hand, used computer from a few years back, that is a pretty good chance that the applications that you installed or want to install in your PC will run slow as the computer hardware industry is very fast paced that the hardware of today will become obsolete in a year. With that said, if you have an old computer, there is no other way of making it faster but replacing it with a new one or upgrading the main components of it like the system board, memory or the central processing unit.

Second, there are many software application today that is very memory extensive that it eats up most of the RAM (Random access memory) of the computer which leaves nothing for the Operating System or for other application.

Third possible reason is that the unit is infected by a virus which also consumes a lot of your computer’s processing power. Viruses can come from an external drive or from online in the websites that you are visiting.

How to make a new computer run faster?

From the same reason given above, the same things can be done to make a computer run faster.

For the first and second point or item, like mentioned, there is no better way than to upgrade.

The third one is to have a antivirus scan and clean the computer up. But in my experience it is better or completely erase the computer (format the system) and reinstall the OS and application to make sure that the virus is completely removed. (Of course, you have to make backup of your important files)

You may definetly need to clean up your PC.
Here is instructions about how to clean your PC: http://www.wikihow.com/Clean-Your-Comput…
1. Download a nice PC cleaner from http://www.pc-registry-repair.cc
(System cleaner is a best choice)
2. Run the cleaner and clean up your PC.
3. Restart your PC

Summary: User instruction on how to setup public-key authentication.

In setting up the ssh public-key authentication between servers, local and remote, we have to generate the key pairs and transfer it to the remote/server.

Client Side

The publickey authentication method is enabled by the SSHtectia package by default. A functional ID’s key pair can be generated using the ‘generate_keys’ script (may be located in /export/opt/SSHtectia//util/ or depending on your installation). That script, ‘generate_keys’, is use to generate user key pairs: id_dsa_2048_a and id_dsa_2048_a.pub (default names) in the centralized key location:

/etc/opt/SSHtectia/keys/

The script also creates an ‘identification’ file in /etc/opt/SSHtectial/keys/ that contains the name of the private keys:

# more identification
# SSH Tectia private key
IdKey /etc/opt/SSHtectia/keys/%U/id_dsa_2048_a

# OpenSSH private key
IdKey /etc/opt/SSHtectia/keys/%U/id_dsa

Don’t forget to substitute the private key filename for ‘id_dsa_2048_a’ or ‘id_dsa’ if you are using a different naming convention. If several key pairs are used, list private keys on a separate lines.

Server Side

The publickey authentication method is enabled for functional IDs ONLY by the SSHtectia package (how do we know if an account is such?).

Copy the public key file (i.e. id_dsa_2048_a.pub) to the server, to the centralized key location. You can use sftp, copy paste or any other method to do this.

Also copy the ‘authorization’ file (created by the ‘generate_keys’ script) from the cliet to the server’s centralized key location.

Test the connection.. it should work.. It worked on mine.

There’s this 2 new WordPress plugin here in Sysadmindayph dot com (the newest that I installed at least). I just want to share this one for the readers of this blog who is also WordPress user.

The two new plugins here are:

• SEO Smart Link
• Broken Link Checker

SEO Smart Link – SEO Smart Links can automatically link keywords and phrases in your posts and comments with corresponding posts, pages, categories and tags on your blog.

Broken Link Checker – This plugin will monitor your blog looking for broken links and let you know if any are found.

[root@localhost] /work/users> metastat -c d103
d103 p 32GB d100
d100 m 68GB d101 d102
d101 s 68GB c1t2d0s0
d102 s 68GB c1t3d0s0

[root@localhost] /work/users> metastat -p d103
d103 -p d100 -o 32 -b 58720256 -o 127926432 -b 8388608
d100 -m d101 d102 1
d101 1 1 c1t2d0s0
d102 1 1 c1t3d0s0

So from the first metastat -c d103.. that’s a mirrored 68G partition, d100 and a 32G soft partition d103.. We still have around 35G of space.

update: — someone comment please.. this information is incomplete!

The following general guidelines can be used to determine if a restart of NetBackup is required after making changes to the /usr/openv/netbackup/bp.conf file on a system.

• Client daemons such as bpcd, bpbkar, tar and database agents are not persistent and are called only to complete an individual backup or restore. As a result, there are no client daemons to restart. Changes to the bp.conf on a client will take effect when new job streams start, they will not affect jobs that are already started.

• Media Server daemons such as bpbrm, bptm, bpdm are not persistent and are called only to complete a backup, restore, duplication, or other operation. Changes to the bp.conf on a media server should take effect once a new backup or restore is run, they will not affect existing backups. The exception to this is any configuration value that is passed to bpbrm by a master server process such as bpsched. Note: Other Media Manager daemons such as ltid, vmd, avrd and robotic daemons on the media server read from the /usr/openv/volmgr/vm.conf file. These daemons are persistent and typically require a restart of NetBackup.

• Master server daemons bprd, bpdbm and bpjobd are persistent. As a result, these need to be restarted to recognize changes to the NetBackup configuration. The bpsched daemon is called by bprd and is continuously active until all queued jobs have completed. The bpsched daemon must be restarted if jobs are continuously active and the configuration change needs to be picked up before the queued jobs execute.

Anyway, startup scripts of NBU netbackup usually is in /etc/init.d/ aptly called netbackup, or nbuclient. You can check out the scripts also in NBU’s home, i.e /usr/openv/netbackup/bin/goodies

Got a page.. something like “Fault found by metastat” in short description in Remedy…

# metastat | grep Need
State: Needs maintenance
State: Needs maintenance

Which disk?

# metastat d9
d9: Mirror
Submirror 0: d19
State: Needs maintenance
Submirror 1: d29
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 134221440 blocks (64 GB)

Device Relocation Information:
Device Reloc Device ID
c0t2d0 Yes id1,sd@SSEAGATE_ST373307LSUN72G_3HZ6Y1EN000074312CVW
c0t3d0 Yes id1,sd@SSEAGATE_ST373307LSUN72G_3HZ6Y46Y0000743249BK


Check for hard errors to verify if this disk can really be replaced… if it passed (on your criteria), you can try re-syncing it…

c# metareplace -e d9 c0t2d0s5
d9: device c0t2d0s5 is enabled

Verify that it’s doing what it is expected..

# metastat d9
d9: Mirror
Submirror 0: d19
State: Resyncing
Submirror 1: d29
State: Okay
Resync in progress: 0 % done
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 134221440 blocks (64 GB)

And we wait…..

“->” = ILOM
“sc>” = ALOM

.. and since this particular server has the “->” prompt we’re using the ILOM.

From ILOM to Solaris:
-> start /SP/console

From ALOM to Solaris:
sc> console

And of course.. Enter “#.” to return to ALOM / ILOM !!

Send Break on ILOM

set /HOST send_break_action=break
and then
start /SP/console

c)ontinue, s)ync, r)eset? s

bada bing! bada boom!

That’s today’s error,.. you wake up, logged and that’s the request that get slapped on you face…

This is when you try to add or modify a user’s group membership with ‘usermod -G’.. It usually happen when the group has tons of members and using usermod will fail as says that it exceeds… blah blah..

Edit the /etc/group file by hand.. take note though that doing a quick ‘/’ search for the group name will give you a ‘truncated’ message or something…

Find the group name manually, append the user account to the beginning of the list.
